## Description

- description: This paper reports on the application of a near-infrared (NIR) imaging
    system for visualizing heat transfer dynamics from a bulk gadolinium (Gd) sample
    to the surrounding water during the magnetization/demagnetization process of the
    magnetocaloric effect (MCE). The suggested approach relied on the spectral variation
    in water absorption band at 1150 nm wavelength within the NIR spectrum. An experimental
    setup integrated a telecentric uniform-illumination system, a halogen lamp, and
    an NIR camera to enable real-time monitoring of a single magnetization and demagnetization
    cycle induced by an external magnetic field, which was generated by a permanent-magnet-based
    magnetic circuit. Two-dimensional absorbance images captured during this cycle
    clearly depicted the thermal energy generated by the MCE in water. Furthermore,
    an analysis of the thermal boundary layer and the quantification of heat transfer
    from Gd to water provided insights into the dynamics over time. These results
    indicated the potential of our NIR imaging techniques in optimizing thermal–fluid
    interactions within MCE systems, thereby improving the design and efficiency of
    magnetic refrigeration systems.
